VW / Universal 2-Pin 2.8mm Fog Light / HB3 9005 Bulb Socket – OEM 3D0941165A

Direct OEM-specification replacement for the 2-pin waterproof bulb socket used on HB3 (9005) high-beam headlight bulbs and fog lights across Volkswagen Group and universal vehicle platforms. Cross-references VW / Audi OEM part number 3D0941165A (also written as 3D0 941 165A). Uses the 2.8mm contact series in black nylon housing with waterproof sealing — the 2.8mm series is the standard bulb socket contact pitch for HB3/9005 and fog light applications on VW Group vehicles.

What Problem Does This Connector Solve?

The HB3/9005 bulb socket is located directly behind the headlight or fog light assembly, exposed to heat from the bulb, road spray, and vibration. The plastic locking tab fractures over time, allowing the socket to work loose from the bulb base and cause an intermittent or permanent lighting failure. Corrosion of the 2.8mm terminals inside the socket causes high resistance, which reduces bulb brightness and can cause the bulb to overheat. Replacing the socket is a quick repair that restores full lighting performance without replacing the entire headlight or fog light assembly.

Frequently Asked Questions

Q: My VW Passat high-beam is not working — could it be the socket?
